Integrating and interpreting brain maps | doi.org/10.1016/j.ti...

Imaging and recording technologies make it possible to map multiple biological features of the brain. How can these features be conceptually integrated into a coherent understanding of brain structure and function? ⤵️

After 3 years of "just one more analysis", our work on WMH pathophysiology is finally out!

Building on previous post-mortem findings of non-vascular WMHs, we identified a specific signature of neurodegenerative WMHs in vivo using microstructural MRI and normative modeling
